//main.css的内容如下  主要是对一些小的方面进行深度的调控

  /* relevant for the tutorial - start */

    #pictures img { position: absolute; top: 0; left: 0; }

  #sidebar ul li h2 { font-size: 1.2em; margin-bottom: 8px; }

//最后就是最关键的js部分了

$(document).ready(function() { //perform actions when DOM is ready

  var z = 0; //for setting the initial z-index's

  var inAnimation = false; //flag for testing if we are in a animation

  

  $('#pictures img').each(function() { //set the initial z-index's

    z++; //at the end we have the highest z-index value stored in the z variable

    $(this).css('z-index', z); //apply increased z-index to <img>

  });

 

  function swapFirstLast(isFirst) {

    if(inAnimation) return false; //if already swapping pictures just return

    else inAnimation = true; //set the flag that we process a image

    

    var processZindex, direction, newZindex, inDeCrease; //change for previous or next image

    

    if(isFirst) { processZindex = z; direction = '-'; newZindex = 1; inDeCrease = 1; } //set variables for "next" action

    else { processZindex = 1; direction = ''; newZindex = z; inDeCrease = -1; } //set variables for "previous" action

    

    $('#pictures img').each(function() { //process each image

      if($(this).css('z-index') == processZindex) { //if its the image we need to process

        $(this).animate({ 'top' : direction + $(this).height() + 'px' }, 'slow', function() { //animate the img above/under the gallery (assuming all pictures are equal height)

          $(this).css('z-index', newZindex) //set new z-index

            .animate({ 'top' : '0' }, 'slow', function() { //animate the image back to its original position

              inAnimation = false; //reset the flag

            });

        });

      } else { //not the image we need to process, only in/de-crease z-index

        $(this).animate({ 'top' : '0' }, 'slow', function() { //make sure to wait swapping the z-index when image is above/under the gallery

          $(this).css('z-index', parseInt($(this).css('z-index')) + inDeCrease); //in/de-crease the z-index by one

        });

      }

    });

    

    return false; //don't follow the clicked link

  }

  

  $('#next a').click(function() {

    return swapFirstLast(true); //swap first image to last position

  });

  

  $('#prev a').click(function() {

    return swapFirstLast(false); //swap last image to first position

  });

});

 

图片我就不上传了  大家自己找一些图片  换一下名字吧  这样一个翻页相册效果就做出来了 虽然有些冗余  但效果还是不错的
